IEC60068-2-75 up to 50J Impact Testing Machine-Pendulum Hammer Test Apparatus With 1000mm Rigid Arm
IEC60068-2-75 Clause 4.2:
The test apparatus consists basically of a pendulum rotating at its upper end in such a way as to be kept in a vertical plane. The axis of the pivot is at 1 000 mm above the measuring point. Impact Testing Machine
The pendulum is composed of a nominally rigid arm and of a striking element complying with the requirements of table 1 .
For testing heavy, voluminous or difficult to handle specimens, a portable pendulum may be used. It shall comply with the above description but its pivot may be fixed directly on the specimen or on a movable structure. In this case, it shall be ensured that, before the tests, the axis of the pendulum is horizontal, that its fixing is sufficiently rigid, and that the impact point is in the vertical plane passing through the axis.
In all cases, when the pendulum is released, it shall be allowed to fall only under the influence of gravitational force.
